Are there with the quality of a UK or German Uni? (sorry, perhaps it is a stupid question). Actually, yes, they offer distant PhDs - of course I have to find a supervisor or a "promoter", like they call it, but Groningen helps in this way too. I think I have a good subject - Bulgaria is for about 2 months in the EU and a lot of interesting topics can be discussed. But TOEFL is be obligatory?!
